It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "A man being killed while protecting his wealth is martyrdom."
Imam al-Tabarani (may Allah have mercy on him) said: "Su'ayr bin al-Khims (may Allah have mercy on him) narrated it in this way from Abdullah bin al-Hasan (may Allah have mercy on him), from Ikrimah (may Allah have mercy on him), from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both).
And Sufyan al-Thawri (may Allah have mercy on him) narrated it from Abdullah bin al-Hasan (may Allah have mercy on him), and he differed from Su'ayr (may Allah have mercy on him) in his narration (as in the next report)."
It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever's wealth someone seeks to take unjustly, and he fights (in its defence) and is killed, he is a martyr."
And from Abdullah bin al-Hasan (may Allah have mercy on him) another chain is narrated:
It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever's wealth someone seeks to seize wrongfully, and he fights for it and is killed, he is a martyr."
And this hadith is also reported through Ikrimah (may Allah have mercy on him) from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both), other than through the narration of Abdullah bin al-Hasan (may Allah have mercy on him):
Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) relates: I heard the Messenger of Allah (peace and blessings be upon him) saying: "Whoever fights to protect his wealth until he is killed as one wronged, he is a martyr."
This is how it is in the Dar al-Haramayn edition, and probably the correct name is Shu'ayb bin Yahya.
